BRAKE HEAD AND SHOE.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed March 16, 1907. Serial No. 362,758.

T (1 7 7, whom it may concern.-

Be it known that 1, CHARLES P. SMITH, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new ahd useful Improvements in Brake Heads and Shoes; and

I do hereby declare that the following is a full, clear, and exact description of the same,

reference being had to the accompanying drawing, making a part of this specification, and to the numerals and figures of reference marked thereon, in which- Figure 1 is a view showingfthe brake shoe and head connected togethef'and the hanger properly connected thereto, also showing the head connectedto the brake-beam. Figi2 is a detached view of the brake shoe. Fig. 3 is v a detached view of the brake-head showing the hanger detached. Fig. 4 is a view showing a portion of the brake-head and illustrating the hanger partially connected to the brake-head.

The present invention has relation to the,

brake-head and shoe and hanger therefor, and it consists in the novel arrangement hereinafter described and particularly pointed out in the claims.

Similar numerals of reference indicate corresponding parts in all the figures of the draw- 111.

in the accompanying drawing, 1 represents the brake-head, which is provided with the beam connecting flanges 2, which flanges are formed of such a shape that their contact faces will fit the brake-beam 3.

In the drawings I have illustrated the flanges 2,formed to fit what might be termed an I brake beam, but it will be understood tha(t1 any other form of brake-beam may be use On the top or u per portion of the brakehead and above t e connecting flanges 2 is located the rearward extending flange or arm 4, which arm is curved downward so as to form the hanger recess 5, which hanger recess is adapted to receive the bottom or lower end of the hanger 6 as best illustrated in Fig. 1.

It will be understood that the hanger is to be connected to the car truck in such a manner that it can swingwhen the brake shoe 7 is moved to and from the periphery of the car wheel upon which the brake shoe is to come in contact and to be released from contact.

The brake-head 1 is concaved to: correspond with the curvature of the brake shoe 7.

For the purpose of providing ,a means for securely connecting the brake shoe 7 to the brake head 1 the notched flanges 8 are formedupon the back of the brake shoe 7,

which flanges enter the recess 9. It is well understood that brake-shoes must necessarily be frequently removed frornthe brakehead for various causes and for the purpose of removing brake shoes and replacing thesame or others, the flanges 8 are provided with the notches 10 which notches allow for the passage of the cotters 1-1, and when the cotters 11 are placed in the position illustrated in Fig. 1 the shoe will be securely connected to the head by means of the arms 12.

It will be understood that it is not necessary to remove the upper and lower cotters to remove the shoe 7, but when one of the cotters is removed the shoe can be detached by an endwise movement of the shoe with reference to the head.

It frequently happens that when a brakeshoe becomes detached from any cause from the brake-head that the head is liable to become detached from the hanger and drop uponthe road-bed and. in order to provide for this emergency and prevent any dropping of the head in case it becomes detached, or is in case of any undue movement of the head together with the brake-beam the rearward extending flange 4 is providedwith the lateral lugs 4 which will engage the hanger 6 and prevent any displacement of the hanger, ex-

A cept when the iangeris brought into what mi ht be termed a horizontal position or at right angles to its normal position and when brought into a horizontal position or in the EOSltlOIl illustrated in Fig. 4 the hanger can e detached from the head. It will also be understood that the hanger must be brought into the position illustrated in Fi 4 to properly connect said hanger to the liead. The lower end-of the hang r is rounded as illustrated and is so roun ed or curved for the purpose of engaging the rounded edges of the rearward extension 4, thereby preventing any rapid wear as between the hanger and the extension or arm 4.

I have not illustrated the top or upper end of the hanger but it is constructed in the usual manner. In some instances it may be desired to connect a hanger to the extreme top or upper end of the head and for the purose I provide the usual connecting loop 14. If desired the flanges 8 may be provided with the apertures 15, and the head provided with common use.

the apertures 16, thereby providing ameans for connecting the shoe 7 to the heads in It will beunderstood that the back of the shoe 7 should be provided with the rib 17, which rib is seated in the recess 18.

Having fully described my invention what I I claim as new and desire to secure by Leta brake shoe provided with notched flanges,

nected to the brake head, substantially as and for the purpose specified.

, 2. In a brake-head and shoe, the-eo1nb1na tion of a brake beam and a brake head means for attaching the brake-head to the brake-t beam, said head provided With a slot or way,

said notched flanges adapted tobe seated in the groove or way of thebrake-had, said.

brake head provided with a rearward and downward extending arm, said rearward and downward extending arm provided with lateral lugs, substantially as and for the purpose specified. w

ange and a hanger 3. In a brake-headfand shoe, alorakeheadv and a brake beam, a .brakefshoedetaohably connected to the brake head ,i said bralc'e head provided with a rearward and downwardextending arm, saidjarm adapted to receive a hanger, said hangefprovided with ar'ounded I contact portion for" engagement with the rearward extending arm and the rearward extending arm provided with curved por tions upon its bottom or under side, substantially as and for the pur ose specified. '1

4. In a brake-head an shoe, the cornbina tion of a brake-head, a brake shoeprovided withnotohed. flanges, cotters adapted to con.

meet the brake-head and shoe together, said brake-head provided with a rearward ex-- tended arm, said rearward extended arm provided with lateral flanges, a hanger adapted to sup ort the brake-head and the-lower portion 0 the hanger located under the rear- "ward extended arm and intermediate the lateral fianges 'and thebody of the brake-head, substantially as andfor the purpose specified,

In testimony that I claim the above, I- have hereunto subscribed my name in the presence of two Witnesses.
